S1A2272A01 Datasheet, PDF (1/6 Pages) Samsung semiconductor – FM NOISE CANCELLER

FM NOISE CANCELLER
INTRODUCTION
The S1A2272A01 is a monolithic integrated circuit for the FM
noise canceller used in car stereos.
It is used in combination with a PLL FM multiplex demodulator
with a pilot signal canceller.
16−SOP−225A
FEATURES
• Operation voltage range: V_CC = 8V − 15V
• Low quiescent circuit current
• Low distortion: THD = 0.02% at V_I = 300mV
• Pilot signal compensation
• Built-in monostable multivibrator.
• Variable input type noise AGC system.
